I just checked it and it works fine for me (I use firefox). In the article's edit page I did these checks:1. Change administration language interface to Spanish, editor loads fine.2. Change translation drop down to Spanish, editor loads fine.To make sure spanish language files are updated for Elxis 4.4 do this:Go to Site > LanguagesAt the bottom of the page, at "Check translation" section select: Language 1 = en, Language 2 = es, File = com_content.phpClick "Check"On the comparison page see if a language string is missing (especially at the bottom).
